Definitions
- This invention relates to novel peptides which are useful anticoagulant and antiplatelet agents.
- Anticoagulants are useful therapeutic agents in the pharmacological treatment of, for example, acute deep venous thrombosis, pulmonary embolism, acute arterial embolization of the extremities, myocardial infarction, and disseminated intravascular coagulation.
- Prophylactic administration of anticoagulants is believed to prevent a recurrence of embolism in patients with rheumatic or arteriosclerotic heart disease and to prevent certain thromboembolic complications of surgery.
- Administration of anticoagulants has also been indicated in the treatment of coronary artery and cerebrovascular disease. Arterial thrombosis, particularly in arteries supplying the heart muscle and brain, is a leading cause of death.
- Hirullin P18 is a 61-amino acid hirudin-related protein having potent antithrombin activity. Similar to hirudin, it contains a highly acidic C-terminus of significantly different sequence from any other known hirudin variant. The C-terminal fragment acetyl-hirullin P18 40-61 has an antithrombin potency similar to that of acetyl- desulfatohirudin 45-65 . While applicant has discovered that certain amino acids residues of the native sequence are critical to maintaining the antithrombin activity of the fragment, other residues have been found to be less
- hirullin P18 54-61 from hirudin 59-65 suggest a different mode of interaction with thrombin. Nevertheless, the C-terminal functional domain represented by hirullin P18 50-61 appears to be comparable to hirudin 55-65 in terms of its binding to thrombin and its functional role in the protein.
